Hi Dixie
It's because we're "programmed" that way by "respectable" ppl and by movies and magazines and books. If you see the early 60's biker movies, the biker "chicks, babes, bitches, etc" are dressed in a certain way (and act a certain way) to make us think they're "hard assed, cheap, and loose". And then we're taught that that's a bad way to be, (if you're a girl) because "men like to play with those kind of girls, but they DON'T marry them". It's all about programming.
I think it gives biker gals a bad wrap. Personally, I like seeing biker women in leathers. I think it's sexy.
I always felt sorry for those women who looked down on me. They lead boring little lives compared to the bikers who love nothing better than to go for a put on a sunny day through the woods either on their own bikes or wrapping their arms around the man they love and experiencing life with the breeze in their faces and the freedom of the road.
